Title: Electromagnetic flow meter
Inventor: OKANIWA HIROSHI
IPC: G01F1/60
Filed: 1991-10-21
Abstract: PURPOSE:To enable a timing signal which is in synchronization with a commercial power supply noise to be created. CONSTITUTION:A noise signal which is detected by a noise-detection means 8 is delayed by a delay time which is predetermined by a delay circuit 11 and a timing signal is created by a timing-generation part 9 based on the signal. Also, when no noise signal is obtained, a pseudo noise signal with the same cycle as that of the noise signal is generated by a pseudo noise generation means 13 while it is delayed by a scheduled time where the noise signal is obtained, thus enabling a timing signal to be created according to the pseudo noise signal. Therefore, the timing signal and the noise signal are synchronized with each other, thus obtaining a noise reduction effect.
